Patent CA-2051741-A1 (CA)
Title: Method of end to end verification of primary and secondary data base in a process control system
Inventor: MCLAUGHLIN PAUL F
IPC: G06F15/177
Filed: 1991-09-18
Abstract: Data bases of a first and second input output processor (IOP), which are primary and secondary slave IOPs, respectively, are synchronized, and communications by a master controller is made only to the first IOP.   Each IOP is executing the same tasks utilizing their own clocking systems.  A method for periodically verifying that the first and second data base remain synchronized comprises the steps of sending a sync-verify type message to the first IOP.  The second IOP eavesdrops on the communications, and when the second IOP recognizes that the message is addressed to the corresponding primary slave IOP, accepts the message.  Upon detecting the message is of the sync-verify type by each IOP, operations by each IOP are suspended.  A number is generated by each IOP of its own data base, the number being indicative of the contents of the information stored in the data base.          A status request type message is issued by the master controller to the first IOP for the number generated by the first IOP, and a status request type message is issued by the master controller to the second IOP for the number generated by the second IOP.  Upon receipt of the numbers by the master controller, the value of the number generated by the first IOP is compared to the value of the number generated by the second IOP, thereby determining that the information stored in the first and second data bases are the same when the numbers compare.

Title: Field effect transistor
Inventor: NAKAJIMA SHIGERU
IPC: H01L29/812
Filed: 1992-01-13
Abstract: Abstract of the Disclosure The invention provides a FET by forming a channel layer in layer including "n" type impurity at high concentration, which is sandwitched by a first semiconductor layer and a second semiconductor layer lightly doped with impurity.  Therefore even when electrons in the channel layer obtain high energy, the electrons in this arrangement rush out essentially to the second semiconductor layer excelling in electron carrying characteristic, thus a travelling speed of the electrons in the channel layer is not lowered.          Furthermore the channel layer being formed in layer and allowed to include impurity at high concentration, the current drive capability can be improved.

Title: Method and device for loosening skin tissue
Inventor: PITZEN SYLVESTER A
IPC: A61N1/32
Filed: 1991-02-05
Abstract: A massaging pad is pressed against discrete areas of a subject person's scalp and worked from side to side to thereby move the skin relative to the underlying skull. The pad (20) is cloth material that is compressible as necessary to avoid the discomfort of pressing a hard metal probe against the scalp. Electrical current is passed through the pad and into the subject person's scalp by connecting the pad to an electrical conductor from an electrical current generating device (12) which generates oscillating voltage to the pad in a low range and at a variation of voltages. The pad includes a highly conductive metal bulb, e.g. of copper metal coated with silver and gold, and a moistened padding, e.g. wool that surrounds the bulb. The ground contact is hand held by the subject person so that electrical current is directed down through the skin layers during the massaging process.

Patent CA-2087419-A1 (CA)
Inventor: YAMAMOTO ALBERT K
IPC: F16B21/08
Filed: 1993-01-15
Abstract: PATENT APPLICATION PAPERS OF ALBERT K. YAMAMOTO, FRANK J. COSENZA AND JAMES R. POTTER ABSTRACT OF THE DISCLOSURE A fastener assembly for securing a first panel member to a second panel member in a spaced-apart relationship. The fastener comprises a tubular shank portion having first and second end portions, a cavity being formed in the shank portion. A first spring member is secured on the outside of the shank portion and has openings near the first end of the shank portion to enable steel ball members to protrude therefrom. Inside the shank portion cavity is a stepped pin member that is spring loaded and held in place by a combination of the shank portion spring ball retention feature and step angles formed on the pin member. The ball members are in the retracted position until usage, held there by the first spring member. When the fastener is pushed into an aperture formed in the second panel member, the first spring member is compressed back toward the first shank portion of the fastener and moves away from the ball members it normally forces inward. As the fastener passes through the aperture, the ball members are still in the retracted portion since the aperture diameter is approximately the same size as the inside diameter of the first spring member that previously contained it in the shank openings. When the fastener passes through the aperture beyond the ball members, a second spring member, positioned behind the pin, pushes the pin forward and forces the ball members to expand radially thus securing itself to the second panel member completing the installation. At this point, there is a compressive load between the retracted first spring on the panel member and the radially expanded locked ball members. To remove the fastener, a tool is inserted in a recess formed in the pin member and the pin is pushed axially toward the first end of said shank portion, compressing the second spring member and allowing the ball members to retract inwardly. As the ball members retract to the proper depth, the fastener quickly exits the hole due to the compressed first spring ejection load and the first panel member is free to be removed. Simultaneously, the first spring member positions itself over the ball members to maintain them in the retracted position.
